This is an excellent introductory book for philosophical inquiry dealing primarily with four areas of human thought, the nature of belief as a first step to knowledge, the nature of knowledge and an analysis of radical skepticism of knowledge via individual and cultural subjectivism, along with discussion of the viability of paradigms, a discussion of the nature of human beings from a number of perspectives, and finally, a discussion of moral and ethical inquiry. Jim Hall's writing style is humorous and personable, not once talking down to his readers. I'd recommend this book as both light reading from cover to cover, and as a highly engaging and informative textbook.
